IMPROVEMENT IN DITCHER AND GRADER.

The Sched'ul'e referred to lin these Letters Patent and making part'. of the same To all whom 'it may concern Be it known that we, J. G. Sissox and LARK Dn- LANA, of Arcola, in the county'ot' Douglas, and in the State of Illinois, have invented certain new and useful Improvements in Ditcher and Gradcrgl and do hereby declare that the following is a. full, clear, and exact description thereof'7 reference 4being had to tbe accompanying drawings and to the letters of reference marked thereon, making a part ot' this speeltication.

'Ihe nature of our invention `consists in the construction ot' a ditcher and grader, which is provided on the mold-board side with two or more plows, which can be adjusted to any desired depth, by means of levers, pivoted to the side ofthe frame.

Figure l represents a side elevation of our invention.

Figure 2 is a plan view of the same.

Letter A represents the fra-une ofthe ditchcr, which is plated on the land-side with either iron or steelplate, madeto extend.downward below the bottom ot' the frame, so as to cut deeper and more readily, and bending outward, so as to form suction, thus cutting deeper the heavier the pressure is troni the inoldside.

Pivoted to side of the frame there are two or more plows, one being placed near the center and the other at the rear end. The one, B, placed at the end is pivoted between the plating C and a bar extending backward from the traine, and is so constructed that by having a number ot' holes placed one above the other in the plating the plow can be raised and lowered to any desired depth.

Totbe rear end of the frame there is attached a keeper, I), to which the lever G is pivoted, by means of which the plow is secured in a perpendicular position, having its upper end bearing against the rear end of the lever.

The plow H, shown in dotted lines, is pivoted to' the side ot' the fraaie, and is held iu position by the lever K in a similar manner.

Should these plows catch against a stone or root,` by raising the levers to a vertical position, and again starting the team, the plows will change from an upright to ahorizontal position, releasing their points i'oni the obstruction. These plows form suicient suction to overcome the weight onthe mold-board side, and to hohl the land-side tothe ground.

Having thus described our invention,

What we claim, and desire to secure by Letters Patent, is-

'Ihe frame A, plows B and H, lovers G and K, and keeper D, when combined so as to form a. ditcher and grader, substantially asv shown.

In testimony that we claim the foregoing, we have hereunto set our hands this 28th day of July, 1869.
